Best way to fill a transducer wire passthrough

[Biggyniner]

First time I've had to drill a hole through the hull to pass my transducer wire through. What is recommended to fill the hole around the wire to make it water-tight?

I’ve used these in a couple of applications. Works well

I usually use 5200 to fill and seal the hole
